1, first explain the 74ls164 shift chip:74hc164, 74hct164 is a 8-bit edge-triggered shift register, serial input data, and then output in parallel.Data is entered serially through one of two inputs (DSA or DSB), and either input can be used as a high-level enable to control data input from another input. Two inputs either connected together, or the unused inputs terminated high, must not be suspended.Each time the clock (CP) is changed from low to high, the data is shifted right one bit, input t

In clock. the s5pv210_get_arm-clk of C uses the macro samsung_get_base_clock and the related registers, because our clock code was previously implemented using assembly, so we have the arch-s5pc1xx in arch/ARM/include/ASM/clock. h to define these registers:

SVN open firewall port introduction, svn firewall portPreface
Due to the previous laziness, the firewall was shut down after the server was installed with svn. Recently, the server was told to show signs of virus, so the Firewall should be enabled, however, opening the firewall will lead to svn access failure, so now there is a new requirement to open the svn service port.

People who believe in PHP development often get annoyed that 80 ports are occupied by some other service. In the absence of an effective method, you can only continually restart Apache or nginx, or remove software that believes it may be consuming 80 of ports.
Actually, we don't have to be so nervous.
The workaround is as follows:
1. View the program that occupies 80 ports:Open a command prompt, in which you enter: CMD, and then execute the following command:
